VENTILATED WEBBING Filed July '12, 1930 INVENTOR ATTORNEY f Patented 0a. 6, 1931 UNITED STATES PATENT OFFICE GEORGE E. SAUERMANN, OF MIDDLETOWN, CONNECTICUT, ASSIGNOR TO THE RUSSELL MANUFACTURING COMPANY, OF MIDDLETOWN, CONNECTICUT, A CORPORATION OF CONNECTICUT I VENTILATED WEBBING Application filed July 12, 1930. Serial No. 467,403.

This invention relates to fabrics and is concerned more particularly with an elastic fabric or webbing especially suitable for incorporation in garments by reason of its being so constructed as to afford ventilation and elasticity both warp-wise and filling-wise.

Elastic webbing is now used extensively in the manufacture of such garments as garters and the like, and it has also been employed in pajama trousers to replace the usual drawstring. Webbing for such purposes is preferably relatively wide so that it will not cause discomfort to the wearer due to binding but such wide webbing has the disadvantage that it fits the body of the wearer snugly over a substantial surface from which it cuts off air circulation.

The present invention is accordingly directedto the provision of an elastic webbing which may be of suflicient overall width to prevent uncomfortable binding and aflords ventilation so that discomfort from this source is overcome. At the same time, the new webbing may have the same resistance to stretch as an ordinary Webbing of the same overall width.

The new fabric includes a plurality of webs of any suitable or preferred weave lying side by side with a space between and connected by a strand which has spaced portions along its length secured to the webs alternately, and intermediate portions which extend across the space. Preferably the portions of the strand connected to the webs are woven therein and held in place by filling or weft strands. For a better understanding of the invention, reference may be had to the accompanying drawings, in which Fig. 1 is a plan view of the new fabric in normal condition, and Fig. 2 is a similar view showing the fabric stretched.

The fabric as illustrated is made up of a pair of webs 10a and 105, each of whichincludes non-elastic warp strands 11, elastic warp strands 12, and filling strands 13. In the construction illustrated there are four elastic warp strands incorporated in each web, one along each edge and two in the body of the web but this arrangement is only one of many which may be employed, although it is preferable to have elastic warp strands at the edges of the webs.

The Webs lie side by side with a space be tween and are secured together by a connectmg element 14 which may take the form of an elastic or non-elastic warp strand. This strand has spaced portions 14a along its length which are secured alternately to the webs and intermediate portions 146 which extend across the space between the webs.

Preferably the portions 14a of the strand are woven into the webs. For this purpose each web is Woven with a separate shuttleand during the weaving, the warps are stretched taut as indicated in Fig. 2 with the strand 14 lying between the warp strands which are to lie at the adjacent edges of the webs. While a portion of the fabric is being woven, the strand 14 is connected to the web 10a by filling strands 13w which extendstrand, it is apparent that it may include adner described.

I claim:

1. A fabric which comprises a pair of webs lying side by side with a space between them, and a connecting warp strand having spaced portions woven into the webs in alternation, the intermediate portions of said strand extending across said space, said space being free of filling strands and said webs and strand all adapted to lie in a single plane.

2. A fabric which comprises a pair of webs lying side by side with a space between them, and a connecting warp strand having spaced portions woven into the opposed edges of the webs in alternation, the intermediate portions of said strand extending across said ditional webs, connected together in the manspace, said s ace being free of filling strands and said webs and strand all adapted to lie in a single plane.

3. A fabric which comprises a pair of webs lying side by side with a space between them, each web comprising warp and filling strands, and a connecting warp strand having spaced portions connected to the webs in alternation by means of filling strands thereof, the intermediate portions of said strand extending across said space, said space bein free of filling strands and said webs an strand all adapted to lie in a single plane.

4. A fabric which comprises a pair of elastic webs lying side by side with a space betw en them, and a connecting warp strand having spaced portions woven into the webs in alternation and intermediate portions extending across said space, said space being free of filling strands and said strand having substantially the same length as the fabric when the latter is stretched to its limit.

5. A fabric which comprises a pair of elastic webs made up of elastic and non-elastic warp strands and fillin strands, said webs lying side by side in a p ane with a space between the adjacent edges thereof, and a connecting warp strand having spaced portions along its length secured alternately to said edges of the webs by filling strands thereof, and intermediate portions extending across said space, said space being free of filling strands.

6. A fabric which comprises a pair of elastic webs made up of elastic and non-elastic warp strands and filling strands, said webs lying side by side in a plane with a space between the adjacent edges thereof, and a connecting warp strand havin 'spaced portions along its length secured alternately to said edges of the webs by filling strands thereof, and intermediate portions extending across said space, said space being free of filling strands and said strand having a length substantially the same as said non-elastic warp strands.

7. A fabric which comprises a pair of elastic webs lying side by side with a space between the adjacent edges thereof, eachweb including elastic and n0n=elastic 'warp' strands and filling strands, and a connecting warp strand having spaced portions along its length lying along said adjacent edges of said webs in alternation and held thereto by filling strands thereof, the intermediate portions of said connecting strand extendin across said space, said space being free of fil ing strands.

8. A fabric which comprises a pair of elastic webs lying side by side with a space between the adjacent edges thereof, each web being made up of non-elastic warp strands, filling strands and elastic warp strands, at least one of said elastic warp strands lying along the inner edge of each web, and a connecting warp strand having spaced portions along its len h lying in contact alternately along said a jacent edges of said webs wit said elastic warp strands and secured to said webs, said space between the webs being free of fillin strands.

9. A fabric which comprises a pair of webs lying side by side with a space between them and a connecting warp element having spaced portions along its length secured alternately to said webs and intermediate portions extending across said space, said space bein free of filling strands and said webs an strand all adapted to lie in a single plane.

10. A fabric which includes a pair of webs lying side by side with a space between them and connected by a warp element extending across said space at spaced points, said space being free of filling strands and said webs and strand all adapted to lie in a single lane.

11. A fabric which includes a pair 0 webs lying side b side with a space between them and secure together by connecting warp means extendin acrom said space at spaced points alternately in opposite directions, said space being free of filling strands and said webs and strand all adapted to lie in a single plane.

12. A fabric which comprises a pair of webs lying side by side with a space between them and connected by a warp strand extending across said space at intervals, said webs being longitudinally extensible and said fabric being transversely extensible, and said space being free of filling strands and said webs and strand all adapted to lie in a single plane.

13. A fabric which comprises a plurality of webs 1 ing side by side with spaces between them, a acent webs being connected by a warp strand extending across said space atintervals, and each of said spaces being free of filling strands and said webs and strand all adapted to lie in a single plane.

In testimony whereof I affix my signature.
